Application filed October 2 2 l 8 97.

T0 all whom t may Concern:

Be it known that I, HENRY B. HAIGH, a citizen ofthe United States,residing in New York, (Brooklyn,) in the county of lKings and State ofNewYork, have invented certain new and useful Improvements in Milk-Cans,of which the following is a specification.

This invention relates to milk-cans, andy more particularly relates tothe construction of the upper or neck portion of the can, and has forits object to provide animproved can having the neck portion thereofreinforced in a peculiar and effective manner and in such a way as topermit the neck of the can to be made of two parts, each oneinterlocking with the other and each reinforcing the other, whereby themouth portion and the breast portion of the can can beconstructedindependently of each other, and thereforewith greaterfacility than when made in one piece, and when placed in positionrelatively to each other will form aneck of superior durability, eachpart of which overlaps the other part In the drawings accompanying andforming part of this specification, Figure l is a verticalsectional'view of a milk-can the upper portion of whichis constructed inaccordance with this invention. Fig. 2 is a vertical sectional view ofthe upper portion of a milkcan, showing a somewhat different form ofconstruction.V Fig. 3 is also a vertical sectional view of the'upperportion of a milk-can, showing still'another form of construction. Fig.4 is a vertical sectional detail View of a part of a milk-can mouth andbreast before the same is assembled in the manner shown in Fig. 1, andFig. 5 is a vertical sectional view of the upper portion of a milk-canwith the reinforcing-strip shown in Fig. 3 removed Similar characters ofreference indicate corresponding parts in the different iigures of thedrawings.

Heretofore milk-cans have been constructed in various ways, one of whichhas been to make the mouth, neck, and breast of the can in one integralpiece or structure, which, aside from the difficulty in obtaining such astructure, has resulted simply in the production of a can which isextremely weak at the neck Serial No, 656,077. (No model.)

portion thereof, where it shouldbe of great strength and rigidity, asthe neck being formed in one piece with the mouth and breast is of thesame thickness as such'breast and mouth, and therefore not beingreinforced it `follows that when the cans are subjected to the ready andeasy construction of the upper portion of the milk-can, while at thesame time so reinforcing the neck portion thereof that the roughhandling or usage of the same will not affect or impair the usefulnessof the can.

` In a general way the upper portion of this can or receptacle comprisesa mouth member having a neck portion and a breast'member also having aneck portion, preferably of the same area as the neck portion of themouth, the neck portion of one member fittingwithin and being preferablycompletely overlapped by the neck portion of the other member and ltheneck portion of one member interlocking with the neck portion of theother member, so that as compared with the mouth and breast portions ofthe can the neck thereof is of greater thickness and rigidity.

In the preferred form thereof herein shown and describedV the flaringmouth member 2 of the can A is provided With'a depending neck portion 3and immediately above such neck portion with an interior annular recess4, Figs. 1 and 4;. The breast member 5 of the can is drawn inwardly toform an upwardly-extending neck portion 6 and shown in one constructionof less diameter than the neck portion 3, so that it can be inserted inand overlapped by said neck portion 3. Each neck portion extends at anangle to its respective breast ormouth member, thereby rendering suchneck part rigid. Before the neck parts are completely assembled the neckportion 6 of the breast member is in this construction' of greater widthor area than the mouth neck portion 3, whereby the upper IOO partthereof is adapted to overlap a portion of the mouth proper above theangle thereof and form locking means for the two neck portions and thebreast and mouth members and also reinforcing means for the mouth at theangle thereof. When the parts are assembled, Fig. l, the neck portion ofthe breast extends upwardly through the neck part 5 and projects abovethe same, such projecting part being bent or turned outwardly at arelatively sharp an gle to form a locking-flange 7, which rests in theannular recess 4 and so locks the neck portions and the breast and mouthmembers together, the upper edge 7 of said flange being flush with theinside face of the mouth. The lower edge of the mouth neck portion 3rests on the breast member and may project slightly below the point ofjuncture of the breast neck portion 6 with the breast, thus protectingsuch juncturepoint. By this construction when the parts are assembled itwill be seen that one neck portion is substantially of the same area orwidth as the other neck portion, so that one completely overlaps andreinforces the other throughout the entire area thereof.

From the above it will be seen that the loeking-liange 7 also serves asa reinforcing means for the mouth member at the point of juncturetherewith of its neck portion 3, and consequently at the mouth angle,while at the same time it will be seen that the actual joint or point ofconnection S of the breast neck portion with the mouth neck portion isat a point remote from the angle of the neck and in a location outsideof the interior of the can, so that the joint is perfectly observableand is accessible for cleaning without requiring special care on thepart of the operator.

From t-he foregoing it will be seen that an improved can is providedhaving a neck of extreme strength and rigidity and heavily reinforced atthe point of greatest strain, each neck portion forming such neck beingof the same width or area, and that the neck is so constructed as toavoid the making of any seam within the can which would be unobservableor inaccessible, thereby avoiding any increased liability (over theordinary cans heretofore in use) of retaining dirt or germs and therebyimpairing the sanitary value of the can.

In the construction of can shown in Fig. 2 the neck is reinforced in thesame manner as the can-neck shown in Fig. l, the neck portions of themouth and breast being locked together in a similar manner. In thisconstruction of can, however, the locking and reinforcing iiange 7 isshown carried by the mouth neck portion instead of by the breast neckportion, it being liared outwardly and fitting with a flush joint intoan interior annular recess 4', formed immediately below the point ofjuncture of the breast neck portion 6 with the breast. In thisconstruction it will be seen that the breast neck portion 6 ismaintained between two outwardly-fiarin g portions of the mouth member,one being the Haring mouth portion 2 and the other the aringlocking-ange 7', the breast neck portion 6 overlapping the mouth portion3 instead of being overlapped thereby, as in Fig. l.

In the construction of can shown in Figs. 3 and 5 the neck may beconstructed similar to either of the forms above described, but isshown, preferably, constructed in a similar manner to the can shown inFig. l and provided with a closed protected space 9, shown herein formedby making the locking-iiange 7 of relatively greater area, as comparedwith the annular recess 4, and adapted to receive an annular reinforcingor stiffening band or member 10, which may be constructed of anysuitable material -such, for instance, as metal-whereby the thickness ofthe neck is treble that of the breast or mouth portions proper of thecan, so that still greater rigidity and strength are imparted to thecan-neck. In practice this ring 10 may be made of a tempered-steel bandof suliicient resiliency and stability to safely sustain the shocks towhich this class of article is necessarily subjected and thereby preventany bending of the neck, which would, if occurring even to a slightextent, prevent the cover from fitting properly.

When the parts have been assembled and firmly locked together, they aresubjected to the usual coating or tinning operation, Whereby the seamsare filled and the joints firmly cemented together by the coating metal,which acts as a soldering medium. In the construction of can shown inFigs. 3 and 5 when this tinning operation has been completed the bandwill be securely closed in and protected in its closed and protectedspace from oxidation by water or by the acids which are formed from anyof the metallic or other fluids that may be left on the can.

From the foregoin git will be seen that the mouth and breast portions ofthe can can be formed of separate members, thereby facilitating theconstruction of the upper portion of the can, while at the same time theweak point and the'one which is usually subjected to the greatest injuryand the roughest usage is thoroughly reinforced and protected, and thatowing to the flush joints the retention of dirt or germs is obviated andthe sanitary value of the can is not impaired, and that, furthermore, bythe construction of cans shown in Figs. l, 3, 4t, and 5 thelocking-joint is observable, so that any dirt or foreign matter formingat such point can be readily 0bserved during the cleansing operation, sothat by the present improvement a can is secured which from a sanitarypoint of view is equal to a can made without joint, while at the sametime is of greater durability and rigidity and more easily constructedthan such a jointless can.

I claim as my invention- 1. A milk-can comprising a breast member IIOprovided with a neck portion; and a mouth member provided with a neckportion, one of said neck portions extending within and being overlappedby the other neck portion, and one of said neck portions having alaringreinforcing and locking flange, and one of said members having anannular recess for the reception of said flaring ange whereby the breastmember and mout-h member are locked together by a Hush-jointinterlocking means.

2. The herein described milk receptacle comprising a mouth memberprovided with a depending neck port-ion and an annular recess above saidneck portion; and a breast member having an upwardly-extending neckportion extending within and overlapped by said mouth neck portion, andhaving a fiaring locking and reinforcing flange seated in the recess ofthe mouth member and forming therewitha flush joint, whereby the mouthneck portion and the breast neck portion are each reinforced one by theother throughout the entire area thereof, and whereby the point ofjuncture of said neck portion is located outside of the interior of thecan.

3. A milk-can comprising a breast member provided with an integral neckportion; and a mouth member provided with an integral neck portion, oneof said neck portions extending within and being overlapped by the otherneck portion to form an annular space intermediate said integral neckportions, and one of said neck portions having a aring reinforcing andlocking flange, and one of said members having an annular recess for thereception of said flaring iiange, whereby the breast member and mouthmember are locked together by a flush-joint interlocking means, andwhereby such interlocking means forms a closure for completely closingsaid annular space. f

4. A milk-can comprising a mouthmember provided with an integral neckportion; a breast member also provided with an integral neck portion,said integral neck portions so overlapping each other and connectedtogether as to form a closed protected annular space intermediate suchintegral neck portions; and a reinforcing band inclosed in said space,intermediate said neck portions, and forming a treble-reinforced neck.

5. The herein-described milk-can comprising a mouth member provided Witha depending neck portion and an annular recess above said neck portion;abreast mem ber provided with an upwardly-extendin g neck portion eX-tending through and overlapped by the mouth neck portion throughout theentire area thereof, and having an outwardly-extending flaring lockingand reinforcing flange seated within the annular recess of the mouthmember and forming therewith a iush joint above the neck of the can,said Haring flange constituting reinforcing means for the mouth memberadjacent to the neck angle thereof; and an annular metal bandintermediate the Vneck portions of said breast and mouth members and ofthe same area as each of the said neck portions, substantially asdescribed.
